How MMMDCXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 600 | DC |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 3647 | MMMDCXLVII |
MMMDCXLVII is written one place at a time, from the largest to the smallest: MMM (3000) + DC (600) + XL (40) + VII (7) = 3647.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMMDCXXXXVII
Why isn't 3647 written as MMMDCXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3647 is MMMDCXLVII.
